Newark Mayor Cory Booker, left, laughs as Mark Zuckerberg, right, founder and CEO of Facebook, talks about his donation of $100 million to help Newark public schools during a press conference at the Robert Treat Hotel in Newark, N.J., Saturday, Sept. 25, 2010. Also there is N.J. Gov. Chris Christie, not in picture.

New Jersey's largest city must produce a list of documents related to its $100 million public schools pledge from Facebook founder Mark Zuckerberg.

A judge issued the ruling as part of a lawsuit brought by a group representing Newark schoolchildren that is seeking more transparency about the donation.

The Associated Press and other news outlets also have made such requests.

Newark initially said that no documents existed and that if they did they were privileged. The American Civil Liberties Union argued the privilege can be claimed only by the governor.

The judge told the city to compile a log about the roughly 50 pages of emails it now says exist.

The $100 million pledge was announced a year ago on "The Oprah Winfrey Show."
